Re: 2011 Malibu Transmission Issue Major Bummer
I just wanted to provide my experience so far, i posted this on another forum where people were talking about tranny issues with their Malibus:
We have a 2011 Malibu with the similar shifting problems, its been in the shop (dealer) twice now, and the first time they said the shift points were all messed up in the computer (some low pressure, some high). After they reset the computer, the problem went away for about a week, then returned.
We returned it to the dealership again and they provided a 2012 Malibu as a loaner, same tranny and motor however it did not have shifting issues like ours.
The service adviser said no problems could be detected in the computer, so he took it home overnight to see if he could duplicate the problem the next morning, and he did in fact feel the problems with shifting.
We picked up the car 2 days ago, and the problem appears to be gone, since we havent had any issues so far (however its only been 2 days.)
According to the service papers, the dealership replaced/performed the following:
1x Valve Body Kit (I assume Seals and Gaskets)
8.8 Qts Fluid.
Emergency Rush Delivery of the Parts from GM
Cleaned Valve Body
(They also washed and vacuumed the car, of course)
What they DID NOT REPLACE:
The 1/2 tank of Gas that was in the tank
Our problem was having a serious 2-3 second delay on the 1-2 upshift when warm or cold, and general poor performance when cold. After a cold start the car would feel as if I was towing a heavy load behind it until fully warmed up. After warm up the car would sometimes appear to lock itself into second (or third) gear after stopping at an intersection, rolling back on even the slightest inclines. We have not had any issues since we picked it up 2 days ago and problem appears to be gone. I did contact the GM 1-800 customer service number before taking it in this second time to make sure they were aware of an issue. It appears there are literally thousands of others having similar issues with this transmission.
